CONTROL DEVICE FOR HYBRID VEHICLE FOR CONTROLLING THE HYBRID VEHICLE WHEN A COLLISION IS DETECTED

摘要

When a collision of a vehicle is detected, a control device performs fuel cut of an engine (14) in a case where the engine (14) is in a driven state, and engages an engine connection/disconnection clutch (KO) in a case where the engine connection/disconnection clutch (KO) is disengaged, whereby the rotational resistance of a motor (MG) is increased by drag of the engine (14) and the rotation speed (Nmg) of the motor (MG) after the collision of the vehicle can be speedily reduced. Consequently, generation of an electromotive force by rotation of the motor (MG) is prevented, and it is possible to speedily complete discharge of an inverter circuit (40).

主权项

1. A control device for a hybrid vehicle, the hybrid vehicle including an engine, a motor, and a clutch provided in a power transmission path between the engine and the motor, the control device comprising:
a collision detector configured to detect a collision of the hybrid vehicle; and a controller configured to:(a) perform fuel cut of the engine in a case where the engine is in a driven state when the collision detector detects the collision; the controller being configured to engage the clutch in a case where the clutch is disengaged when the collision detector detects the collision; and(c) disengage the clutch when a rate of change of a rotation speed of the engine is positive after the collision
